- This is not about Dired, so let's please leave that to one side.

- This is not just code cleanup.  I think 'tabulated-list-mode' gives
  clear benefits to users today.  Sorting is one example which will
  immediately improve.  Mouse support is another.

- I'm not convinced that it's necessary, but I don't see the problem
  with an interactive bookmark menu in bookmark+.el (or any
  third-party package really) that is not directly based on the code
  in Emacs.

Which features are you talking about?

I don't understand this argument.  It seems to be based on the
misunderstanding that 'tabulated-list-mode' somehow limits you to sort
by column.

To my mind, this is the most convincing argument you presented.  Yet
you have not shown any limitations in 'tabulated-list-mode' that makes
it unsuitable for 'bookmark-bmenu-mode'.  Could you please explain
which limitations you see, and how you concretely see them affecting
bookmark-bmenu-mode?

Best regards,
